I have no idea what this procedure would be called, so I didn't search for it. I'm sorry if this is a double post.

Is there a way to double both the total measures and the note length without having to go through and manually change each note?

I've got a piece that goes up to three bars in some places, but goes really slow. I want it to look simpler, i.e. have the eight notes be quarters, the sixteenth eighth, etc. Then I can increase the speed so it will sound the same. Also, I have another part I want to combine with it that has the length doubled, and they're incompatible right now.

Thanks!
